PO ➟ SWR ➟ ALC

• PO : indicates the relative RF output power.

• SWR : indicates the SWR over the transmission line.

• ALC : Indicates ALC level.

4 What is the Automatic Notch Filter?

The Automatic Notch Filter is a narrow DSP ﬁlter that

automatically identiﬁes and attenuates beat tones, tun-

ing signals, CW, etc., even if they are moving and re-

moves them from the receiver passband while pre-

serving the desired signal’s frequency response.

➥ While in the set mode/quick set mode, rotate to

select the set mode item. (p. 70)

➥ This control can act as the memory channel

control or RIT control.

• The RIT function should be turned ON in advance to

activate this control as RIT control. (p. 44)

During [M-CH] acts as RIT control:

Rotate to shift the receive frequency (p. 44).

• Rotate the control clockwise to incerase the fre-

quency, or rotate the control counterclockwise to de-

crease the frequency.

• The shift frequency range is ±9.999 kHz in 1 Hz

steps (or ±9.99 kHz in 10 Hz steps).

4 What is the RIT function?

The RIT (Receiver Incremental Tuning) shifts the re-

ceive frequency without shifting the transmit frequency.

This is useful for ﬁne tuning for stations calling you

off-frequency or when you prefer to listen to slightly

different sounding voice characteristics, etc.

4 What is the Manual Notch Filter?

The Manual Notch Filter is an adjustable narrow

DSP filter that removes tones from CW, SSB, AM

or RTTY signals while preserving the desired sig-

nal’s frequency response.
